21. Resonant switching and vortex dynamics in spin-flop bi-layers
Abstract : This thesis is a study of the static and dynamic behavior of the magne-tization in spin-flop bi-layers, which consist of two soft ferromagnetic layerscoupled by dipolar forces through a thin nonmagnetic spacer. The focus ofthe work is three fold: collective spin dynamics in the anti-parallel groundstate; resonant switching in the presence of thermal agitation; and static anddynamic behavior of the system in the vortex-pair state, with a particularemphasis on the interlayer core-core interaction.

22. Structure and Properties of Perovskite SrTiO3 and Na0.5K0.5NbO3 Thin Films Fabricated by rf Magnetron Sputtering
Abstract : Functional oxide thin films are getting more and more attention due to their unique dielectric, piezoelectric, ferroelectric, magnetic, superconducting properties. This thesis focuses on the growth, compositional control, and structure-property relationships of SrTiO3 and Na0.5K0.5NbO3 thin films. READ MORE

23. Analytical techniques for quality assessment of separated and commingled recycled polymer fractions
Abstract : Different methods for quality assessment of separated andcommingled plastics from household and electronic waste havebeen developed. Especial attention has been given tospectroscopic methods since they are non-destructive andrequire little or no sample preparation at all. READ MORE
